App::CELL::Config(3pm)

NAME
App::CELL::Config -- load, store, and dispense meta parameters, core parameters, and site parameters

SYNOPSIS
    use App::CELL::Config qw( $meta $core $site );

    # get a parameter value (returns value or undef)
    my $value;
    $value = $meta->MY_PARAM;
    $value = $core->MY_PARAM;
    $value = $site->MY_PARAM;

    # set a meta parameter
    $meta->set( 'MY_PARAM', 42 );

    # set an as-yet undefined core/site parameter
    $core->set( 'MY_PARAM', 42 );
    $site->set( 'MY_PARAM', 42 );

DESCRIPTION
The purpose of the App::CELL::Config module is to maintain and provide access to three package variables, $meta, $core, and $site, which are actually singleton objects, containing configuration parameters loaded by App::CELL::Load from files in the distro sharedir and the site configuration directory, if any.

For details, read App::CELL::Guilde.

EXPORTS
This module exports three scalars: the 'singleton' objects $meta, $core, and $site.

SUBROUTINES

  AUTOLOAD
The "AUTOLOAD" routine handles calls that look like this:
   $meta->MY_PARAM
   $core->MY_PARAM
   $site->MY_PARAM

  DESTROY
For some reason, Perl 5.012 seems to want a DESTROY method

  exists
Determine parameter existence.

  get
Wrapper for get_param

  get_param
Get value of config param provided in the argument.

  get_param_metadata
Routine to provide access not only to the value, but also to the metadata (file and line number where parameter was defined) associated with a given parameter.

Takes: parameter name. Returns: reference to the hash associated with the given parameter, or undef if no parameter found.

  set
Use this function to set new params (meta/core/site) or change existing ones (meta only). Takes two arguments: parameter name and new value. Returns a status object.
